A kernel view of critical infrastructure modelling

Abstract: The discussion starts with the concepts of networks and sectoral infrastructures making reference to the recent Council Directive 2008-114-EC which is the basis for the identification of European critical infrastructures. Two arbitrary but interdependent infrastructures are then considered (power station and water works) which form the basis of kernel network that is then subsequently analysed under four different cases of disruption (without recovery). The kernel network therefore idealises a monolith or basic architecture consisting of just two nodes and two edges with the intent to illustrate some of the basic characteristics of the kernel as well as understand what happens in the event of a disruption and how this might propagate with consequent cascading effects. The paper begins by taking primarily a didactic and preparatory approach and then progresses into more detailed and complex modelling by illustrating the same kernel modelled using three modules by Mathworks (MATLAB, Simulink and Stateflow). Later the concepts of fuzziness and fuzzy cognitive maps are introduced and discussed in the context of network modelling. The discussion closes with possible developments of the kernel network and what tools may be exploited to model more complex situations and successfully tackle the resulting challenges.
